I should have 1gig, I have had the service for couple months and not had any issues bar VM usual b's they go through.
I've tested it using Google's test, speedtest.net website and windows app, the speed test app on Android aswell.
All ethernet tests are using good cables, different on each device, usually getting around 950-980 and my wireless performance had always been spot on, usually getting aroun 600-700 on wifi on my phone.
I have tried it both in modem mode with my own router and in router mode.
My speed returns for couple minutes after each reset then drops back down to around 90.
Really feels like a deliberate cap
